Lots of guys screw up right here. Remember, our goal is to reduce the total housing width from 56.5 inches to 50.5 inches. But because the welded-on outer axle-bearing carriers will be reused, we must remember not to simply measure 3 inches from the outmost ends and chop. Instead, the correct way is to measure in 3 inches from where the axle-bearing carriers meet the axlehousing tubes and make the cuts there. Be sure the axlehousing is resting perfectly flat on the chop saw table for straight cuts. Also, be sure to compensate for the 11/48-inch thickness of the chop saw blade.
